Abstract:
Nanotechnology is well recognized as an emerging strategy and being employed successfully to improve the crop growth, productivity, quality, nutrient use efficiency as well as to improve the abiotic stress tolerance in plants. Application of nano-scale fertilizers is one of the possible practices of precision farming that make the crop production systems more efficient, sustainable and environmentally safe by reducing wastage of resources, input, cost and energy. Targeted delivery of nano-scale micronutrients could substantially improve the crop yields, nutrient uptake and recovery and/or fertilizer use efficiency and crop performance under stressful conditions. The NPs are transported within plants through vascular bundles (xylem and phloem), however excess accumulation of NPs in the root and shoot system could induce oxidative stress due to overproduction of reactive oxygen species (ROS) in plants. Application of NPs improves abiotic-stress tolerance in plants by regulating plant physiological processes such as redox regulation, osmotic adjustment and/or activation of antioxidant enzymes. No doubt, application of NPs induces abiotic stress tolerance in plants, however their excess application may cause detrimental effects on morphological, physiological, anatomical and genetic traits in crop plants which largely depends on concentration, size and chemistry of NPs. Overall, application of nanotechnology in agriculture and/or plant science is an emerging field, having both positive and negative effects on plants, however, future research should be focused on the positive effects of NPs in improving growth, productivity and abiotic stress tolerance in plants.
